Embodiment Construction
[0027] The embedded security equipment referred to in the present invention refers to but is not limited to digital hard disk video recorders and digital video servers. Embedded security equipment is the equipment used in the monitoring industry in the security field. The main control chip generally used is a SOC (System On a Chip, System On a Chip) chip, and almost all SOC chips have GPIO (General Purpose Input Output, that is, General-purpose input / output) pins, GPIO pins are a general-purpose chip pin type.
[0028] The embedded security device of the present invention includes a main control chip of the embedded security device and a voltage conversion device, the main control chip of the embedded security device is connected to the voltage conversion device, and the voltage conversion device is used to change the output voltage value according to the operation of the user. The main control chip of the security equipment is used to monitor the voltage value output by the v...

The invention provides embedded type security equipment and a password recovering method thereof. The embedded type security equipment comprises an embedded type security equipment master control chip and a voltage converting device; the embedded type security equipment master control chip is connected with the voltage converting device; the voltage converting device is used for changing an output voltage value according to operation of a user; the embedded type security equipment master control chip is used for monitoring a voltage value output by the voltage converting device; and when the voltage converting device outputs a pre-set voltage value, the embedded type security equipment master control chip can recover a current system password to a default password. With the adoption of the embedded type security equipment and the password recovering method thereof disclosed by the invention, the default password of the embedded type security equipment can be rapidly recovered by the user under the limited condition, the defects that the period of a traditional password recovering method is long and the cost is high are overcome, the recovering efficiency of the password of the embedded type security equipment is improved, and the cost for maintaining the embedded type security equipment by manufacturers is reduced.
Description
technical field [0001] The invention relates to the technical field of embedded security equipment, in particular to an embedded security equipment and a password recovery method thereof. Background technique [0002] Embedded security devices, such as DVR (digital video recorder, digital video recorder) and DVS (digital video server, digital video server), there are two types of users who can log in to the device to operate, one is the administrator user, and the other is is an ordinary user. Generally, there is only one administrator user, which is created by the device manufacturer before the device leaves the factory. The administrator’s initial password (default password) is set by the manufacturer before the device leaves the factory. After the device arrives at the user, the user can log in to the device with the default password. , and change the default password to the user's own administrator password to ensure device login security. The administrator password can...
